I just bought an EOS 3 to compliment my 5D. I am in the middle of the first roll of film to test drive it. Observations: 1. I like the eye control. I calibrated it (and recalibrated 2 more times) and then went out to play. It works pretty well. 2. I like the ability to average multiple spot meter readings. 3. I think I will like the DEP setting, but I haven't used it yet. 4. I was prepared for loud shutter trips. However, it is louder than I expected. Between the shutter and the film advance, there is no doubt that the picture has been taken. 5. The last film SLR I owned was a Pentax K1000. My how things have changed!
